A gutter system incorporating a gutter clip and a gutter hanger to affix a gutter to a retaining clip attached to a fascia board of a building, thereby eliminating the need to place holes in the gutter with screws or nails. The gutter hanger is constructed of a single piece which has an intermediate section which is disposed substantially within the gutter and spans the width of the gutter to maintain the shape and structural integrity of the gutter. The gutter hanger has a contiguous platform disposed along its intermediate section for slidably and detachably attaching a leaf protection support apparatus. The leaf protection support apparatus has a groove that snugly but slidably receives the platform of the gutter hanger. The leaf protection support apparatus extends toward the roof of the building, and has a vertical member terminating in an angled member extending upward to support a leaf protection device.
